Every cat is different. I find that with Justice, our bedroom is the only room that has an AC in it. More times than not, you can find her in my room sleeping. I've even left the AC on and left my bedroom door open so that if she got to cold, she could go out of the room, but everytime, she remains in my room sleeping. I've shut her out of my room before while I was cleaning and when I open the door back up, shes right there at my door waiting to get back in. My daughter just got a kitten and when he's downstairs in the livingroom, he just looks so hot and miserable and mostly lays down and takes it easy, when I bring him up to my room, he perks right up and is a bouncing ball of joy.
